La présente invention se rapporte à une bande extrudée d'étanchéité pour caisses de véhicules, comportant un élément profilé de fixation, en caoutchouc plein, à section en U, dans lequel est The present invention relates to an extruded sealing strip for vehicle bodies, comprising a U-section solid rubber fastening element in which is

De telles bandes d'étanchéité comportent très souvent un bourrelet d'étanchéité en caoutchouc mousse, coextrudé avec le profil de fixation et ayant, en coupe transversale, une forme qui convient à sa destination, par exemple tubulaire et sensiblement circulaire, ou encore une section en forme de lèvre, le bourrelet d'étanchéité étant porté par l'une des branches de la section en U Such sealing strips very often comprise a foam rubber sealing bead, coextruded with the fastening profile and having, in cross-section, a shape that is suitable for its purpose, for example tubular and substantially circular, or a section in the form of a lip, the sealing bead being carried by one of the branches of the U-shaped section

In addition, because the velvet ribbon is mounted on the front fastening profile

Ce "caoutchouc mousse" est avantageusement un caoutchouc expansé à structure cellulaire fine, dont les alvéoles fermés ont un diamètre qui, approximativement,ne dépasse pas 1 à 2/10 de millimètre, et qui This "foam rubber" is advantageously an expanded rubber with a fine cellular structure, the closed cells of which have a diameter which does not exceed approximately 1 to 2/10 of a millimeter, and which

Le procédé selon l'invention est caractérisé en ce que The method according to the invention is characterized in that

Si le bourrelet d'étanchéité et la couche de revêtement If the sealing bead and the coating layer
sont de même matière, ce bourrelet et cette couche peuvent être co- are of the same material, this bead and this layer may be co-
extrudés en une même alimentation de la filière d'extrusion. Dans ce cas, il suffit de deux extrudeuses: l'une, qui est la principale, ayant pour rôle d'alimenter la filière avec un mélange destiné à la formation du profil de fixation qui doit envelopper complètement la bande d'armature en têle métallique, et la seconde alimentant la filière avec un jet de mélange dilatable qui s'y répartit, vers l'ouverture de celle-ci pour former le bourrelet d'étanchéité et extruded into the same feed extrusion die. In this case, only two extruders are required: one, which is the main one, whose role is to supply the die with a mixture intended for forming the fastening profile which must completely encase the wire-reinforced reinforcing strip. and the second supplying the die with an expandable mixing jet which is distributed thereto towards the opening thereof to form the sealing bead and
vers l'ouverture pour la formation de la couche de revêtement. towards the opening for the formation of the coating layer.
Toutefois, les matières servant à réaliser le bourrelet d'étanchéité etla couche de revêtement sont généralement différentes l'une de l'autre, la raison principale étant que le caoutchouc mousse destiné à constituer la couche de revêtement doit, de préférence, être moins maléable que celui du bourrelet d'étanchéité. En outre, il peut être bon que la couche de revêtement contienne certains However, the materials used to make the sealing bead and the coating layer are generally different from each other, the main reason being that the foam rubber to form the coating layer should preferably be less malleable that of the sealing bead. In addition, it may be good for the coating layer to contain some
